I don't think the OP wanted double subscripts.  If the OP really wanted 
"heavily underscored code snippets", something like:

Code snippet:  ~a_variable_deleteThisAndItWorks~

seems like the way to go.

See (info "(org) Emphasis and monospace")

That way the latex is

: \texttt{a\_variable\_deleteThisAndItWorks}

and that idiom would properly render html as

: <code>a_variable_deleteThisAndItWorks</code>

rather than

: a<sub>variable</sub><sub>deleteThisAndItWorks</sub></p>

as in OPs case. The latter is valid html, but doesn't seem quite like the 
right thing to do for code snippets.

HTH,

Chuck
